How did Galileo prove that objects in vacuum fall with uniform acceleration?

The remarkable observation that all free falling objects fall with the same acceleration was first proposed by Galileo Galilei nearly 400 years ago. Galileo conducted experiments using a ball on an inclined plane to determine the relationship between the time and distance traveled.

What did Galileo say about free falling objects?

Galileo’s law of free fall states that, in the absence of air resistance, all bodies fall with the same acceleration, independent of their mass.

How did Galileo come up with the idea about motion that objects of different masses dropped simultaneously from same height will reach the ground at the same time?

According to Galileo if we drop two objects of different masses from a height both will reach the ground at same time because the value of gravity which pulls them downward is same. Acceleration is equal to force divided into weight of an object.

What can you say about the acceleration of objects falling in a vacuum?

Free Falling Object Motion. An object that falls through a vacuum is subjected to only one external force, the gravitational force, expressed as the weight of the object. The acceleration is constant and equal to the gravitational acceleration g which is 9.8 meters per square second at sea level on the Earth.

How did Galileo proves that Aristotelian concept of motion is not correct?

As we have seen, Galileo’s concept of inertia was quite contrary to Aristotle’s ideas of motion: in Galileo’s dynamics the arrow (with very small frictional forces) continued to fly through the air because of the law of inertia, while a block of wood on a table stopped sliding once the applied force was removed because …

Why objects fall at the same speed in vacuum?

If your heavy and light objects are in a vacuum, then they fall at the same speed. This is because they only have one force acting on them: gravity.

How did Galileo explain the uniform motion?

Galileo chose to define uniform acceleration as the motion in which the change of speed v is proportional to elapsed time Dt, and then demonstrate that this matches the behavior of real moving bodies, in laboratory situations as well as in ordinary, “un-arranged,” experience.

How did Galileo’s ideas on falling objects differ from Aristotle’s?

Aristotle says that the heavier things are, the quicker they will fall, whereas Galileo felt that the mass of an object made no difference to the speed at which it fell. They concluded that Aristotle was correct and it is the force of gravity that makes this happen.

What is Galileo’s concept of falling objects in his experimentation?

Galileo Galilei—an Italian mathematician, scientist, and philosopher born in 1564—recognized that in a vacuum, all falling objects would accelerate at the same rate regardless of their size, shape, or mass. He arrived at that conclusion after extensive thought experiments and real-world investigations.

What forces were acting on the objects dropped in the vacuum?

The forces that were acting on the objects in the vacuum were gravity and mass.

Why did Galileo’s experiment work in a vacuum?

Galileo dropped objects that “pierced the air” similarly, so in a sense only gravitational force was acting on them, which allowed them to hit the ground at the same time. In a vacuum (earth is not a natural vacuum environment), there are no forces acting on the objects other than gravity.

What is Galileo’s equation for a falling body?

Following his experiments, Galileo formulated the equation for a falling body or an object moving in uniform acceleration: d=1/2gt2.

What is Galileo’s theory of gravity?

Galileo proposed that if it were possible to create a vacuum, where only gravity affected the objects, then regardless of their mass, falling objects would travel the same distance in the same time. *Objects falling under the same conditions will reach the ground at the same time.

What did Galileo prove about the speed of the ball?

Galileo proved that the ball had an additional force that affected its velocity that was constant. Galileo had come to understand every object had 10“forces acting upon objects could be broken into independent components,” but he also proved that the planet had a constant uniform acceleration acting on all objects.
